Ineed a student is asked to balance an equation by using the half-reaction method. he determines the two half reactions as shown below.(first image)what should he write as the final, balanced equation? (second image)(third image)(fourth image)(fifth image)

The goal of this experiment was to answer the question "what is the effect of a gas' temperature on its volume? " you formulated the hypothesis below. hypothesis: if a fixed amount of gas is heated, then the volume will increase because the heat will cause the molecules of gas to move faster and further apart. to test this hypothesis, you changed the of the gas between 0 and 100°c (273 and 373 k) and calculated the resulting of the gas.
